• The FAS Deployment Plan joins up the individual investment plans of operators, airports and air traffic control bodies, with the FAS roadmap, to establish a credible delivery programme. The plan describes the new ATM capabilities that will be deployed in the UK and UK/Ireland Functional Airspace Block between 2013 and 2020. It represents the first step towards delivering the FAS proposal, and in turn the European wide Single European Sky initiative to modernise the operations of the aviation sector.
